Artist <a href="http://lisanilssonart.com/">Lisa Nilsson</a> uses rolled up pieces of Japanese mulberry paper to create these amazingly intricate anatomical formations that mimic something you might see in a biology textbook. The technique is known as paper filigree or <a href="http://en.wikipedia.org/wiki/Quilling">quilling</a>, and Nilsson assembles each piece over the course of several weeks by following the details from a photograph of a cross-section, which helps to make her work incredibly detailed. The result is her Tissue Series, an intricate study of our internal organs formed entirely from <a href="http://inhabitat.com/tag/paper-art/">paper</a>.
